|#309||invalid||Holder can be Is_Empty and Is_Universal_String simultaneously|
I guess, that was maid intentionally, to make output variables typed in SQL, but it's counter-intuitive when reasoning about values. Maybe there should be a more explicit distinction between empty string and non-empty string? I mean, Is_Universal_String should return False for Data'Tag => League.Holders.Universal_String_Tag and Is_Empty => True unless some non-default argument was specified to Is_Universal_String.
Those who are willing to check tag of empty holder should do it in a manner distinct from everybody else who only need to deal with values and only want to see Is_Universal_String = True when there is a real string inside.
|#370||fixed||Upgrade default mysql charset from utf8 to utf8mb4|
MySQL encoding named 'utf8' actually does not support code points above BMP. Higher multilingual planes are only available in 'utf8mb4' encoding.
|#117||fixed||Makefile.install gnatls commands produce blank lines|
In the Makefile.install file, there are several gnatls | sort | sort > file.list commands that cause the subsequent install commands to choke.
The reason for this is that the gnatls command output starts with a blank line, at least on FreeBSD. The blank line is propagated to sort and uniq, so the install command throws an error on the first line.
I fixed it by removing the blank line by piping the output of the gnatls command to "grep -v '$$'" before the sort command.
I have attached a diff file to illustrate the changes need to install matreshka on FreeBSD, including a fix for xargs -a.
